Nice idea but I would be worried about tearing. I don’t know what the actual paper weight is but it looks in the “bible paper and cheap newsprint” range (~40-60gsm), which will probably rip as soon as a belt/orbital sander crosses the glue line into the looser leaves (and you have to cross the glue line to debind, and by nature that line isn’t normally straight, because glue does not melt evenly). You also destroy the spine, making it harder to identify issues at a glance. A thermal binding machine would likely melt the glue in 45-90 seconds without those risks. And you might even be able to rebind after the scan with fresh glue strips using the same machine, assuming you don’t have to cut the cover wrap.
